Facts You Need To KnowThe national speed limit on motorways for cars and motorcycles 70 mph.
When joining a motorway, give way to traffic already on the motorway.

Vehicles towing trailers cannot travel in the right-hand lane of a motorway (unless all other lanes are closed).

The maximum speed limit for them is 60 mph.

The left-hand lane on a motorway can be used by any vehicle.

The left-hand lane should be used for normal driving.

Use the centre and right-hand lanes for overtaking.

Green studs run between a motorway and its slip road.

White studs run between the lanes on a motorway.

Amber studs run between the central reservation and the carriageway.

Red studs run between the carriageway and the hard shoulder.

The hard shoulder should normally only be used for stopping in an emergency. You can, however, travel on the hard shoulder when signs direct you to do so.

An Emergency Refuge Area is an area on a motorway for use in cases of emergency or breakdown.

If you breakdown but can't get to the hard shoulder you should turn on your car's hazard warning lights.

If you breakdown on a motorway and need to call for help it may be better to use one of the emergency roadside phones as this way your location will be accurately known.

If you use a mobile phone to call for help, you can check your location from the marker posts on the left.

Most of the emergency phones are linked to the police, however, some are linked to the Highways Agency Control Centre.

Highways Agency Traffic Officers are able to stop and direct anyone on a motorway.

A red cross displayed above a lane means do not travel in the lane.

A crawler lane on a motorway is found on a steep gradient.

A number displayed above a lane i.e. '50' means the speed limit for the lane is 50 mph.

If you get puncture on the motorway, you should use an emergency phone and call for assistance.

Continuous high speeds on motorways make vehicle breakdowns more likely.

If traffic ahead of you slows or stops suddenly you can turn on your hazard warning lights for a short time to warn traffic behind you.

In a contraflow system there are likely to be lower speed limits.

Contraflow systems are used to reduce traffic bunching.

You should stop on a motorway:
If red lights show above every lane When told to by the policeWhen signalled by a Highways Agency Officer
The following cannot use a motorway:
Learner car drivers Farm tractors and other slow-moving vehicles Cyclists Learner motorcyclistsMotorcycles under 50cc Horse riders

Motorway Rules Theory Questions
Evaluate  Reset
The correct answer is highlighted in red, as is the official DSA knowledge and understanding for each question.

Qu.1 - Mark one answer When joining a motorway you must always
A. use the hard shoulder
B. stop at the end of the acceleration lane
C. come to a stop before joining the motorway
D. give way to traffic already on the motorway
You should give way to traffic already on the motorway. Where possible they may move over to let you in but don’t force your way into the traffic stream. The traffic may be travelling at high speed so you should match your speed to fit in.
Qu.2 - Mark one answer You break down on a motorway. You need to call for help. Why may it be better to use an emergency roadside telephone rather than a mobile phone?
A. It connects you to a local garage
B. Using a mobile phone will distract other drivers
C. It allows easy location by the emergency services D. Mobile phones do not work on motorways

On a motorway it is best to use a roadside emergency telephone so that the emergency services are able to locate you easily. The nearest telephone is shown by an arrow on marker posts at the edge of the hard shoulder. If you use a mobile, they will need to know your exact location. Before you call, find out the number on the nearest marker post. This number will identify your exact location.

Qu.3 - Mark one answer After a breakdown you need to rejoin the main carriageway of a motorway from the hard shoulder. You should
A. move out onto the carriageway then build up your speed
B. move out onto the carriageway using your hazard lights
C. gain speed on the hard shoulder before moving out onto the carriageway D. wait on the hard shoulder until someone flashes their headlights at you

Wait for a safe gap in the traffic before you move out. Indicate your intention and use the hard shoulder to gain speed but don’t force your way into the traffic.
Qu.4 - Mark one answer What colour are the reflective studs between a motorway and its slip road?
A. Amber
B. White
C. Green D. Red

The studs between the carriageway and the hard shoulder are normally red. These change to green where there is a slip road. They will help you identify slip roads when visibility is poor or when it is dark.
Qu.5 - Mark one answer On a three-lane motorway which lane should you normally use?
A. Left B. Right
C. Centre
D. Either the right or centre

On a three-lane motorway you should travel in the left-hand lane unless you’re overtaking. This applies regardless of the speed at which you’re travelling.
Qu.6 - Mark one answer You are joining a motorway. Why is it important to make full use of the slip road?
A. Because there is space available to turn round if you need to
B. To allow you direct access to the overtaking lanes
C. To build up a speed similar to traffic on the motorway D. Because you can continue on the hard shoulder

Try to join the motorway without affecting the progress of the traffic already travelling on it. Always give way to traffic already on the motorway. At busy times you may have to slow down to merge into slow-moving traffic.
Qu.7 - Mark four answers Which FOUR of these must not use motorways?
A. Learner car drivers B. Motorcycles over 50cc
C. Double-decker buses
D. Farm TractorsE. Horse riders F. Cyclists
Learner car drivers and motorcyclists are not allowed on the motorway until they have passed their practical test. Motorways have rules that you need to know before you venture out for the first time. When you’ve passed your practical test it’s a good idea to have some lessons on motorways. Check with your instructor about this.
Qu.8 - Mark one answerImmediately after joining a motorway you should normally
A. try to overtake
B. re-adjust your mirrors
C. position your vehicle in the centre lane
D. keep in the left-hand lane
Stay in the left-hand lane long enough to get used to the higher speeds of motorway traffic.
Qu.9 - Mark one answer You are allowed to stop on a motorway when you

A. need to walk and get fresh air
B. wish to pick up hitchhikers
C. are told to do so by flashing red lights D. need to use a mobile phone

You MUST stop if there are red lights flashing above every lane on the motorway. However, if any of the other lanes do not show flashing red lights or red cross you may move into that lane and continue if it is safe to do so.

Qu.10 - Mark one answerYou are travelling along the left-hand lane of a three-lane motorway. Traffic is joining from a slip road. You should
A. race the other vehicles
B. move to another lane C. maintain a steady speed
D. switch on your hazard flashers

You should move to another lane if it is safe to do so. This can greatly assist the flow of traffic joining the motorway, especially at peak times.
Qu.11 - Mark one answer On motorways you should never overtake on the left unless
A. you can see well ahead that the hard shoulder is clear
B. the traffic in the right-hand lane is signalling right
C. you warn drivers behind by signalling left
D. there is a queue of slow-moving traffic to your right that is moving more slowly than you are
Only overtake on the left if traffic is moving slowly in queues and the traffic on your right is moving more slowly than the traffic in your lane.
Qu.12 - Mark one answer The aim of an Active Traffic Management scheme on a motorway is to
A. prevent overtaking
B. reduce rest stops
C. prevent tailgating
D. reduce congestion
Active Traffic Management schemes are intended to reduce congestion and make journey times more reliable. In these areas the hard shoulder may be used as a running lane to ease congestion at peak times or in the event of an incident. It may appear that you could travel faster for a short distance, but keeping traffic flow at a constant speed may improve your journey time.
Qu.13 - Mark one answerWhy can it be an advantage for traffic speed to stay constant over a longer distance?
A. You will do more start-stop driving
B. You will use far more fuel
C. You will be able to use more direct routes
D. Your overall journey distance time will normally improve
When traffic travels at a constant speed over a longer distance, journey times normally improve. You may feel that you could travel faster for short periods but this won’t generally improve your overall journey time. Signs will show the maximum speed at which you should travel.
Qu.14 - Mark one answer On a motorway what is used to reduce traffic bunching?
A. Variable speed limitsB. Contraflow systems
C. National speed limits
D. Lane closures

Congestion can be reduced by keeping traffic at a constant speed. At busy times maximum speed limits are displayed on overhead gantries. These can be varied quickly depending on the amount of traffic. By keeping to a constant speed on busy sections of motorway overall journey times are normally improved.
Qu.15 - Mark one answerYou are driving at 70 mph on a three-lane motorway. There is no traffic ahead. Which lane should you use?
A. Any lane
B. Middle lane
C. Right lane
D. Left lane
If the left-hand lane is free you should use it, regardless of the speed you’re travelling.
